I need to pull a fifth wheel (15,000lbs) a thousand miles. My water pump just went out. It was the stock high output type. For my purposes, will replacing with the stock variety be fine, or is there a better one out there?
The 99+ with the spin on fan clutch is the desireable one(ac delco oem seems to be the best casting), and the kennedy fan clutch or the hayden 2886 seem to work best. If you really are pulling 15k, go slow and be careful. That is ALOT of weight to be hauling with one of these trucks, let alone a 6.5l.
